Flagging in the Backend: Shipping API's with Flask and LaunchDarkly

on YouTube ↗51m

" summary

A React front end talks to a Flask backend that uses the LaunchDarkly server SDK to toggle behavior at runtime; feature flags carry JSON configs (one contains a DB connection string) and target identities for gradual rollouts and per-user testing. Demo apps switch UI and database targets live (Wi‑Fi causes some lag) and the platform claims init under 100 ms and updates under 200 ms. Key pieces: Flask backend, LaunchDarkly server SDK, JSON flag with DB connection.
